Mount Peake Vanadium-Iron-Titanium Project
The vanadium-iron-titanium deposit discovered by TNG in 2008 is located within the Neoproterozoic sediments of the Georgina Basin. The ore body is hosted by a differentiated basic sill with minor ultrabasic layers. The predominant rock type is olivine gabbro and the mineralised unit is defined by a high concentration of magnetite.
